Me and my wife has recently got a male 9 weeks old kitten. It comes from a good house, so it's already been treated for fleas and (most importantly) litter trained. According to its old owner, it used to eat pretty much any brand of wet and dry food.
However, the first days we had it it refused to eat anything at all we gave it. It didn't seem stressed or scared, just refused to eat even though it was begging for food. Then I tried putting some canned tuna in his wet food and, lo and behold, it ate the whole lot in a jiffy. In the meantime we also managed to find a brand of dry food it eats, so now he has that too.
Now, I know that you shouldn't feed a cat just canned tuna because of mercury accumulation and supplement deficiency, but the latter shouldn't be a problem as it's mixed with regular cat food. So, my question is:
How much canned tuna can a cat eat per day? We're using Lidl (UK) branded tuna in spring water, Here's some pictures of ingredients and nutritional values. It eats approx. between 10g and 15g of tuna per day (I've actually weighted it).
I don't mind adding tuna to its food for the rest of its life, as long as it's safe for it. Thank you.
